Cad Earth Crack — 2021

Using a DJI Phantom 4 RTK, engineers captured sub-centimeter imagery of a 500m long fissure in a desert alluvial fan.

The drone data was stitched to produce a GeoTIFF and a dense point cloud. The resulting 3D mesh highlighted the crack's sinuous path. cad earth crack 2021

The GeoTIFF was attached to AutoCAD Civil 3D 2021 using the MAPIINSERT command. The earth crack was then traced using a 3D Polyline. Using a DJI Phantom 4 RTK, engineers captured

Use the _MAPTRACE tool in AutoCAD Map 3D 2021 to semi-automate the digitization of the crack centerline based on contrast differences in the raster image. Workflow 2: Modeling the Subsurface "Crack" Surface A surface trace is insufficient. Engineers needed to model the shear plane. In 2021, this was done using Feature Lines and Grading Tools . The GeoTIFF was attached to AutoCAD Civil 3D
